Zero Five sits at the lighter end of what Thornbridge makes. The grain bill — pale ale, crystal and Munich malts — gives just enough backbone without making things heavy, and the orange peel addition is a small but noticeable touch that lifts the aroma and adds a faint pithy quality to the mouthfeel. Amarillo provides the citrus character you'd expect: lemon up front, then peach and apricot. The Munich malt brings a little warmth. The finish is dry and clean with moderate bitterness — nothing sharp, just enough to stop it tasting like juice. It's a sensible, low-calorie option for regular drinking rather than a special-occasion beer. At 0.5%, it sits comfortably in the session range.
